Motor Insulation Class

Motor insulation level refers to the level of heat resistance of insulating material, grade a, e, b, f, h. Allowed temperature refers to the motor's temperature increase compared with the ambient temperature limits. Insulation temperature rating of a-class e-class b-f-h-level, the highest allowable temperature (℃) 105 120 130, 155, 180, 1、temperature winding (k) 60 75 80 100 125, performance reference temperature (℃) 80 95 100 120 145
